After a few weeks, we’re going to use your reports to figure out where we think the cheapest and most expensive places in the U.S. are to buy gasoline.

To take part, tell us how much it costs you on average to fill up in your local area, along with how the rising gas price is affecting you.

Or perhaps you live in an area where gas is still well below the $4 mark? Tell us why you think your local gas prices have stayed so low.

Let us know in the Comments below, and be sure to tell us the county and state you live in to help us with our mapping process. We’d also love to hear from people from outside the U.S., although we won’t be including that data in our survey.
